| 摘 要： | The influence of surface roughness on the performance of zinc-rich paint(ZRP) coatings was studied.Electrochemical impedance spectroscopy(EIS) measurements were used to assess the corrison prevention performance of the ZRP coatings.Furthermore,the EIS data of the steel-ZRP-sea water system were interpreted according to equivalent circuit models and the corresponding parameters were derived to assess the coating deterioration with time.The results show that the rougher surface favors better protection effect of the ZRP coatings.The protection potential of ZRP coatings for the standards and codes of practice is -0.78V(vs SCE).
